다국어 초록 (Multilingual Abstract)

The dispersing behaviors of oligomer-type anionic surfactants, cooligomers of diethyl maleate(CmD-Na) or maleic anhydride (CmM-Na) and C₄∼C_(16) alkyl vinylether, which have a different alkyl chain length of the hydrophobic group or degree of polymerization, were studied on the aqueous suspension of α- and β- copper phthalocyanine and carbon black particles. In case of the side alkyl chain length of C₄∼C_(10) 0f CmD-Na, the dispersing actions were good in the concentration range of 0.01 to 0.1%. Especially, side alkyl groups played an important role in the orientation adsorption on the surface of pigment particles, and oligomers having smaller degrees of polymerization were more effective in the dispersing action, but did not affect the dispersability of carbon black.
